As many people hit middle age, they often start to notice that their memory and mental
clarity are not what they used to be. We suddenly can’t remember 46 we put the keys just a
moment ago, or the name of an old brand we used to love. As the brain fades, we refer to these
occurrences as “senior moments”. 47 seemingly innocent, this loss of mental focus can
potentially have a damaging impact on our personal well-being.
Neuroscientists, experts who study the nervous system, are increasingly showing that there’s
actually a lot that can be done. It 48 out that the brain needs exercise in much the same way
our muscles do, and the right mental workouts can significantly improve our basic cognitive
functions. Thinking is essentially a 49 of making connections in the brain. To a certain extent,
our ability to excel in making the connections that drive intelligence is inherited. 50 , because
these connections are made through effort and practice, scientists believe that intelligence can
expand and fluctuate 51 mental effort.
Now, a new Web-based company has taken it a step 52 and developed the first “brain
training program” designed to actually help people improve and regain their mental sharpness.
The Web-based program 53 you to systematically improve your memory and attention
skills. The program keeps track of your progress and provides detailed feedback 54 your
performance and improvement. Most importantly, it 55 modifies and enhances the games you
play to build on the strengths you are developing - much like an effective exercise routine requires
you to increase resistance and vary your muscle use.

参考答案: D
参考解析: 本题考查句子前后逻辑关系。therefore“因此”表示因果关系，用于引出结果；moreover“而且”表示递进关系；otherwise“否则”表示条件关系，相当于 if not；however“然而”表示转折关系。前一句强调的是智力是与生俱来的（inherited），而后一句则认为是可以通过脑力活动（mental effort）产生变化，前后句意明显存在转折关系。
